Five new nickel(II) complexes [Ni(L)NCS] (1b), [Ni(L)N-3] (2), [Ni(L)N(CN)(2)] (3), [Ni(L)OAc] (4) and [Ni(HL)SO4] (5) of a thiosemicarbazone HL (where HL = 2-benzoylpyridine-N(4)-phenylthiosemicarbazone) including pseudohalides like thiocyanate, azide and dicyanamide have been synthesized and characterized by elemental analysis, magnetic susceptibility, FT-IR, electronic and NMR spectroscopic techniques. The interesting amido-iminol tautomerism enables the pro-ligand to exist in amido form as well as deprotonated iminol form thereby functioning as tridentate NNS donor, coordinating through pyridyl nitrogen atom, azomethine nitrogen atom and amido/iminolate sulfur atom in the complexes. The crystal structures were established by single crystal XRD analysis. Two different single crystals of the compound thiocyanato complex were obtained with and without DMF solvent molecule having triclinic and monoclinic lattices with P (1) over bar and P2(1)/n space groups respectively. Also, the compound 2 is having a monoclinic lattice with P21/n space group. Nickel(II) exists in distorted square planar geometry in all the complexes. Further DFT calculations were carried out at B3LYP/TZVP level of theory to obtain an insight on the stability and the nature of frontier orbitals. Finally, electrostatic potential plots mapped on optimized geometries substantiate the noncovalent interactions found in their respective crystal structures. (C) 2018 Elsevier Ltd.

A new aroylhydrazone ligand, 2-benzoylpyridine-4-methoxybenzhydrazone (BPMBH). and its two cobalt(III) complexes, [Co(BPMB)(2)]NO3 center dot 1.5H(2)O (1) and [Co(BPMB)(2)]Cl center dot 2H(2)O (2) have been synthesized and structurally characterized. The synthesized compounds are physico-chemically characterized by CHN analysis, molar conductivity, magnetic susceptibility measurements and spectroscopic techniques like MS, IR, UV and NMR. The high molar conductivity values of the complexes confirmed the presence of counter ions in the lattice of the cationic complexes. The molecular structure of the aroylhydrazone and its complexes have been resolved using single crystal XRD studies. In the solid state, the aroylhydrazone exists in the amido form as evident from the IR and XRD studies. The tridentate nature of the NNO donor aroylhydrazone was also confirmed from the IR spectral studies. XRD studies reveal that in all complexes, the tridentate aroylhydrazone coordinates to the Co(III) center via pyridine nitrogen, azomethine nitrogen and iminolate oxygen and found to possess distorted octahedral geometry. The complexes are bis-ligated cationic complexes in which chloride and nitrate ions act as counter ions. The antibacterial and antifungal activities of the aroylhydrazone and its Co(III) complexes have been screened against bacterial species Staphylococcus aureus, Enterobacter aerogenes, Bacillus subtilis, Streptococcus pyogenes, Klebsiella pneumonia, Salmonella typhi and Escherichia coli. The antifungal activity was also checked using fungi Aspergillus niger, Penicillium chrysogenum and Rhizopus oryzae. From the activity data we can infer that the metal complexes have better biological activity than the metal free ligand against the bacterial and fungal species which were tested.

With a one-pot assembly method, two copper-containing Keggin-type polyoxometalate-based metal-organic frameworks (POMOFs), i.e., [Cu-6(I)(trz)(6){PW12O40}(2)] (HENU-2, HENU = Henan University; trz = 1,2,4- triazole) and [Cu-3(I)(trz)(3){PMo12O40}] (HENU-3), were successfully prepared and structurally characterized. These two compounds, which are generated by the extension of a crown-like {Cu-6(trz)(6)} macrocycle-based sandwich-type structural unit, possess identical noninterpenetration 3D frameworks except for the polyanions difference. Additionally, both of them are assessed as highly effective heterogeneous catalysts in facilitating the oxidation of alkylbenzenes to ketone products in the presence of tert-butyl hydroperoxide. Under optimized conditions, HENU-2 can achieve a 95.2% conversion of diphenylmethane in 20 h with a 100% selectivity toward benzophenone, and it was reused for three runs with constant high activity, which outperforms most POM-based catalysts for this catalytic reaction.

I found the field of Biochemistry & Molecular Biology very interesting. Saw the article Metal-free photocatalysts for the oxidation of non-activated alcohols and the oxygenation of tertiary amines performed in air or oxygen published in 2020.

This protocol describes the use of 9-fluorenone as a cheap and non-toxic photocatalyst for the oxidation of non-activated alcohols performed under the irradiation of a blue light-emitting diode. It also describes the use of the similarly cheap and non-toxic photocatalyst rose bengal for the selective alpha-oxygenation of tertiary amines to produce the corresponding amides in a selective way using the same light source. We have provided detailed instructions on how to assemble the light-emitting diode equipment and set up the photocatalytic reaction, where an oxygen atmosphere is created with an O-2-filled balloon. Further details are provided using four example reactions that illustrate how this system works: alcohol oxidation to prepare terephthlalaldehyde and androstanedione, and amine oxidation to make 2-phenyl-3,4-dihydroisoquinolin-1(2H)-one and (4-((4-chlorophenyl)(phenyl)methyl)piperazin-1-yl)m-tolyl)methanone. The times needed to perform these photocatalytic reactions are 18, 76, 22 and 54 h, respectively. We believe that this protocol represents a robust methodology for the late-stage modification of amines and the selective oxidation of steroids. Cheap and non-toxic photocatalysts 9-fluorenone or rose bengal are used to oxidize non-activated alcohols or oxygenate tertiary amines, respectively, under irradiation from a blue light-emitting diode.

An expeditious, high-yielding synthesis of rare alpha-fluoroepoxides and alpha-fluoroaziridines through the addition of the unkown fluoroiodomethyllithium (LiCHIF)-formed via deprotonation the commercially available fluoroiodomethane with a lithium amide base-to carbonyl-like compounds is documented. The ring-closure reactions, leading to alpha-fluorinated three-membered heterocycles, rely on the diversely reactive C-I and C-F bonds. Excellent chemoselectivity was observed in the presence of highly sensitive functionalities-aldehyde, ketone, nitrile, alkene-which remained untouched during the homologation sequence.

The enantiopure Schiff bases (RorS)-1-(p-R-1-C6H4)-N-(phenyl(pyridin-2-yl)methylene)ethanamine (R-1= H and OCH3) are synthesized from reaction between the 2-benzoyl-pyridine andchiral-amine (RorS)-1-(p-R-1-C6H4)ethylamine, respectively. These Schiff bases react with the copper(II) acetate to give distorted-tetrahedralbis[(RorS)-1-(p-R-1-C6H4)-N-(phenyl(pyridin-2-yl)methylene)ethanamino-kappa N-2,N]-Delta/?-Cu(PF6)(2)in the presence of NH4PF6. A conformational change fromcis- totrans-isomer occurs in solution and thereby, the copper(II) coordinates to the solelytrans-form to provide the complexes. Cyclic voltammograms demonstrate two quasi-reversible one electron charge transfer processes for the Cu2+/Cu(+)and Cu+/Cu(0)couples in acetonitrile. ECD spectra reveal expected mirror-image relationships and indicate enantiopurity or enantiomeric excess of theRorS-ligands and their associated complexes in solution. Comparisons of experimental and simulated ECD spectra suggest induced chirality at-metal center, which diastereoselectively provides the Delta-Cu-Ror ?-Cu-Sdiastereomer as major product in solution. DFT/TDDFT optimized structures and excited state properties correspond well to the experimental results.

Developing efficient heterogeneous catalytic systems based on easily available materials and molecular oxygen for the selective oxidation of alkylarenes is highly desirable. In the present research, NiMn hydrotalcite (Ni2Mn-LDH) has been found as an efficient catalyst in the oxidation of alkylarenes using molecular oxygen as the sole oxidant without any additive. Impressive catalytic performance, excellent stability and recyclability, broad applicable scope and practical potential for the catalytic system have been observed. Mn3+ species was proposed to be the efficient active site, and Ni2+ played an important role in stabilizing the Mn3+ species in the hydrotalcite structure. The kinetic study showed that the aerobic oxidation of diphenylmethane is a first-order reaction over Ni2Mn-LDH with the activation energy (E-a) and pre-exponential factor (A(0)) being 85.7 kJ mol(-1) and 1.8 x 109 min(-1), respectively. The Gibbs free energy (Delta G(not equal)) was determined to be -10.4 kJ mol(-1) K-1 for the oxidation based on Eyring-Polanyi equation, indicating the reaction is exergonic. The mechanism study indicated that the reaction proceeded through both radical and carbocation intermediates. The two species were then trapped by molecular oxygen and H2O or hydroxyl species, respectively, to yield the corresponding products. The present research might provide information for constructing highly efficient and stable active site for the catalytic aerobic oxidation based on available and economic material.
